Japan regulators return to Boeing 787 battery maker

Japan’s transport regulators were returning to the Kyoto headquarters of GS Yuasa Corp., which makes the lithium-ion batteries used in Boeing's grounded 787 jets, for a second probe Tuesday, Bloomberg News reported. Investigators had already visited GS Yuasa on Monday.

Investigators were also sent to the U.K. to visit an unnamed valve actuator maker for the 787, Akihiro Ohta, Japan’s transport minister, said.

Meanwhile, the largest buyer of Boeing’s 787 Dreamliner says that Boeing has done a good job of communicating as it faces problems that have grounded its 787s all over the globe, The Wall Street Journal reported.

According to Henri Courpron, CEO of International Lease Finance Corp., ILFC is scheduled to receive its first 787 in April and there are no plans currently to change that schedule. Customers don’t appear to be having second thoughts about their 787 orders, he told the Wall Street Journal.

"On one hand, we hope for a quick solution, but they need to come up with a fix that resolves the issue fully," said Courpron, who was previously a senior executive at Airbus.

Meanwhile, Norwegian Air Shuttle Chief Executive Bjorn Kjos said Boeing has told the airline to expect its first 787 Dreamliner in April, Reuters reported.

"They say it is going to be fixed soon; they have a plan. They say it will be delivered according to the schedule," Kjos said at an Airline Economics conference in Dublin.
